Good entry-level notebook. Unfortunately useless for laymen because BIOS bug.

The laptop itself is well built for the price range and stands firmly on the table.

Otherwise the performance of the APU for everyday office applications is sufficient, surfing with more than 10 tabs, music and video playback (Amazon Prime HD) without jerking. Even the one or other game is running at the native resolution (1366x768) with medium details fluently (DotA2, LoL, CS: GO). In 3DMark 2011, the notebook comes on acceptable 1830P. An increase in output (20-30%), I was able to achieve a second RAM bar, because the built-up APU dual-channel benefits, in contrast to their predecessors. Installed by the way an AMD R6 M255DX as Crossfire solution that can only intrude, but can not be used as a primary display adapter. Thus, the APU zwackt always something from memory from (512MB)

The biggest drawback was the delivery of a faulty BIOS in conjunction with Windows 8.1. After a Windows 8.1 update, the notebook will not boot on delivery. I have a notebook safely 3 times reinstalled before I could make the Patch identify before it crashes. After looking around I could find out that it was due to a faulty BIOS. On the Lenovo side there is a "newer" BIOS 2014 for the Model Z50-75 and with this start the notebook (after a new fresh installation) even after Windows Updates and then runs correctly.

If you can live with a reflective display for this laptop is certainly a good entry-level solution for everyday use.

Pro:

- Good performance APU in the price range
- SSHD facilitates booting (SSD is still recommended)
- Games for even partially useful (faster than the Intel iGPUs)

Cons:

- Glossy display
- Faulty BIOS

Conclusion:

Definitely preferable to all notebooks in the price range up to 350 with Intel Celeron N (Atom) processors. If you want to completely give up games, for a notebook with Intel i3 U is perhaps an alternative. Otherwise, the AMD APUs are here to continue the P / L winner.
